Confessions of a (pregnant) Bell! During an appearance on the Conan show Tuesday, Jan. 22, actress Kristen Bell revealed she has a pregnant sex tape -- not with husband Dax Shepard, but for her racy Showtime series House of Lies!

"There was a storyline in the second season where my character at work has a sex tape coming out. She brings it into work and shows it to everybody and no one cares," the new mom to 10-month-old daughter Lincoln told Conan O'Brien. "I was 7-months pregnant at the time and they were fitting me in these negligees and I just had this huge beer belly and I was, you know, pretending to act in a sex tape," the 33-year-old star recalled to the TBS host. "Now I can forever look at my daughter and say, 'oh you were present for that,'" she joked.

Showing off her slim post-baby body Tuesday in a three-quarter-sleeved leather dress, the 5'1'' actress said her costars would taunt her for the sexy pregnant scenes filmed for the show: Adam Brody, who plays Bell's boyfriend this season, affectionately referred to their TV sex scenes as "our threesomes."

Meanwhile, there was one guy who really liked her pregnant bod: the Showtime star's hubby Shepard! "Dax mentioned that he loved it when you were pregnant," O'Brien commented during the interview. "What was that all about?"

"He says he likes some meat on my bones -- he phrased it as 'there's more of you to love,'" Kristen Bell told Conan O'Brien of her husband Dax Shepard.

"He says he likes some meat on my bones -- he phrased it as 'there's more of you to love,'" Bell responded. The petite blonde provided even more details on how her pregnancy affected Shepard: "He felt like he was with a completely different woman," she shared. "He said he felt like he was cheating on me."

Not one to care about the comment, Bell added, "That's pretty exciting if you're married and you know, you can feel like you're with someone else, so he loved it."

"Sorry if that's too progressive for everybody!" she said to the audience.
